I think it's more like that you are signalling by your use of HTTPS at all, and the packet body itself is encrypted nonsense.

Hiding information in the protocol layer while the bulk content that is "supposed" to contain the meaning is present but actually meaningless. Or for a physical analogy the payload of the envelope vis a decoy and the real information is hidden in the way the flap is sealed.

It's not even meaningfully similar, let alone exactly that way.

Well, if your HTTPS packets are somehow more retarded than your HTTP packets, yes.
